"These companies recognize that helping employees integrate
home and work leads to a more successful business and culture,"
says Carol Evans, president of Working Mother Media, in a
press release.

To compile the list, which is now in its twenty-ninth year,
Working Mother surveyed more than 200 companies on their
leave policies, workforce representation, benefits, childcare,
advancement programs, and flexibility policies, among other
things — as well as the availability, usage, and tracking of
these programs.

"We compile this list to raise awareness of the issues that
working mothers and all employees face in the workplace, and to
encourage the development programs to address these issues,"
Jennifer Owens, editorial director of Working Mother Media,
told Business Insider.

In total, these 100 companies employ almost 2.1 million people in
15 industries. About one million, or 46% of them are women.

On average, these companies offer seven weeks of fully paid
maternity leave, and three weeks of fully paid paternity leave.
Many also give new moms additional, partially paid time off (six
weeks, on average) — and offer an average
of five weeks of fully paid adoption leave, according
to Working Mother magazine.
